Beyond Means: Topological Causal Effects under Persistent-Homology Ignorability
Researchers have introduced a new framework for causal inference that utilizes persistent homology to analyze changes in outcome distributions beyond simple averages. This topological approach can detect significant shifts in data shape that traditional mean-based methods might miss, even when the average outcomes remain the same. The proposed method defines topological analogues of average treatment effects and demonstrates their identifiability under specific ignorability conditions, offering a more nuanced understanding of causal relationships.
